IMPROVEMENT IN BED-PLATES FOR PAPER-MILL ENGINES.

Specification forming part of Letters Patent No. 178,205, dated May 30,1876 application iiled July 24, 1815.

To all whomjt may concern:

Beit known that I, WILLIAM E.'TAYLOR, of Fulton, in the county ol'Oswego and State of New York, have invented a new and valuableImprovement in Plates for Paper-Mill Engines; and I do hereby declarethat the following is a full, clear, and exact description of theconstruction andoperation ofthe same, reference being had to the annexeddrawings, making a part of this specification, and'to the let! ters andfigures of reference marked thereon.

4Figure 1 of the ,drawings is a representationof a plan view of myplate. Fig. 2 is an end view of the same, and Fig. 3 is a transversevertical sectional view thereof'.

This invention has relation to the bed-plates against which the rotarycutters of a paperpulp engine Operate to reduce the rags; and the natureof my invention consists in the arrangement between two parallel caps orplates, of a suitable length to fit the roll, of a number of diagonalcuttingfplates with intermediate filling-pieces of wood, all of whichcutting-platcs are parallel to each other and are secured to the baseofthe box by a process of casting, as Will be fully understood from thefollowing description.

For the purpose of `more fully representing my invention and improvement,Ihave shown, in Fig. 1,. the bed-plate applied in apaperpulpenginc with the cutting-roller. removed. It will be observedthat all of the cuttingplates a are diagonal to the side-s or caps A Aof the box inclosing them, and that these plates a are parallel to. eachother 'from one end to the other of said box, with thin wooden. stripsor filling b between them. Y The cutting-plates a are arranged withreference to the rotation of the cutting-roller, so that the rags willbe worked toward the midfeather,77 or central partition, which willcause the rags in the current to turn over and more thorpassed throughsaid blades and also through the lianges of the bed B.

The bed-plate or revolving cylinder-is adi' justable vertically upwardor downward, to allow for the wear of the knives in the operation lofthe machine.

The metallic knives in the bed-plate would obviously be less liable towear from friction than the wooden lling, which latter, it is found inpractice, is worn away more Vrapidly than the knives, by the friction ofthe rags agitated by the beater, on the wooden filling, thus alwaysleaving the ,knives to'project above the wooden lilling.

What I claim as new, and desire to secure 1 by Letters Patent, is-

' As a new article of manufacture, a bed-plate for paper-pulp engines,consisting of the parallel plates A A, the diagonal cutting-plates a.,secured to the base of the box, as described,

and the intermediate filling-pieces of wood, all constructed andarranged for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of tw'o witnesses.

WILLIAM E. TAYLOR.
